According to (our iffy translation of) Famitsu, Muramasa: The Demon Blade will be playable in two different modes: "Musou" and "Shura." Musou mode may be best-suited for fans of previous Vanillaware action-RPGs like Odin Sphere: it focuses on character leveling rather than action. Shura mode is all action, with less emphasis on strategy. We don't know how the modes differ mechanically, but it may be as simple as easier enemies in one mode and fewer character customization options in the other.
Along with this news, Marvelous released new screens of Muramasa. As usual, yum. Muramasa comes out April 9 in Japan, which is not fair at all. It's out in Europe in spring of 2010, and in North America sometime this year. But probably not next month. %Gallery-33431%
